Some LED Modules in my Ticker aren’t working

Verify that the LED Module is receiving power

1. Remove the first LED Module that is not showing content. With a phillips head screwdriver, remove the screws securing the LED Module onto the Cabinet. The screws should be removed in numerical order starting with #1. Hold the LED Module to ensure it does not fall unsupported once #6 is removed.
   
2. Remove the module directly to the left of the first Module you removed. E.g. using the diagram below, if you, while facing the Ticker removed Module 4, remove Module 5 next.
   
3. Disconnect the two CAT5 cables plugged into the back of the LED Modules. Then look at the Power Status LEDs, as shown below. Note if the power indicator on either module is lit. Note: The number of power indicators and their color may vary from this picture.
   
4. Reassemble: Plug the Cat5 cables back into the Modules, and secure them to the Ticker cabinet with the screws. Start with screw 6 (top middle). Report back the status of the power indicators to your support representative. 
   

Content stops scrolling at a specific module

The below steps require removing modules. See the Module Replacement article for directions on removing modules. Before doing any module replacement, confirm that the Ticker is powered off.

Note: For clarity sake, all modules in the steps below will be their original module number above, even when they are moved around.  

1. Remove the module directly to the right of the module that is not showing content. In the above image, that would be Module 3.
2. Remove the last module on the ticker. In the above image, that would be Module 5.
3. Swap Modules 3 and 5. For greater clarification, this means Module 5 is now where Module 3 used to be, and Module 3 is where Module 5 used to be.
4. Power on the Ticker. If the Ticker scrolls data to all modules, this means that the output of Module 3 was the problem, and since there is no output after the last module in the Ticker, the Ticker will work as expected.
5. If the Ticker behaves the same way as it was originally, this means that that the issue may not be Module 3, and instead is Module 4.
6. Power off the Ticker, and swap Modules 4 and 5. For greater clarification, this means Module 4 is now at the end of the Ticker, and Module 5 is where Module 4 used to be.
7. Power on the Ticker. If the Ticker scrolls data to all but Module 4, this means that the input of Module 4 is the problem, and it needs to be replaced.
8. If the Ticker behaves the same way as it was originally, this means that the issue may be the power supply at the module that shows no content. Follow the steps in the Ticker Power Supply Replacement article.

Seeing 0.9st on some modules

This issue can occur when communication across the modules in their daisy chain format is somehow corrupted. This issue can typically be resolved by swapping modules, specifically, swap any modules experiencing issues, including not working as expected or displaying 0.9st on them, with the last module in the Ticker. Replace as many modules experiencing the issue with modules near the end of the Ticker until all are showing correct content.

In most cases, modules that were previously showing 0.9st will starting working as expected when the communication issue is corrected by moving that module to a new location on the Ticker.
